[Wikipedia] Limited Range, Endangered Species Status: The Cuyamaca Cypress only verifiably exists in the headwaters area of King Creek in the Cuyamaca Mountains of the Peninsular Ranges system, south of Cuyamaca Peak within San Diego County in extreme Southern California. It is an IUCN Red List Critically Endangered species, and a California Native Plant Society Inventory of Rare and Endangered Plants listed Seriously endangered species.[1][9] The entire native (world) population of the tree was reduced down to thirty to forty individual trees by the 2003 Cedar Fire.
